Solution. A simple proof uses the law of the excluded middle: A ∨ ¬A Loading to natural deductions: there is the Curry-Howard isomorphism between natural deductions and simply typed terms and cut-elimination in the first corresponds to β-reduction in the latter (see [Howard 1980]). A different definition of natural deduction is flag style natural deduction defined by [Fitch 1952]. Because deduction rhymes with reduction, you can easily remember that in deduction, you start with a set of possibilities and reduce it until a smaller subset remains.
